MOVABLE VENTILATOR FOR VAULTS.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed June 23, 1908. Serial No. 439,993.

To all whom it may concern.

Be it known that we, FREDERICK S. HoLMEs, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, and GEORGE L. DAMON, a citizen of the United States, residing atPittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Movable Ventilators forVaults, of which the following is a specification.

The object of our invention is to provide a convenient and effectivemeans for establishing ventilating connection between the inside of avault and an outside air passage, while I the vault is open, which meansis readily removable or withdrawn within the vault previous to closingthe door or doors.

With this end in view, our invention con sists in arrangement of partsas well as the construction thereof, hereinafter fully described andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section through aportion of a vault and its vestibule with our improved ventilatorapplied thereto and in position assumed when the vault is open, thewithdrawn position being shown in dotted lines; Fig. 2 is a horizontalsection of the vestibule and a portion of the vault with the ventilatorshown in plan and in position of use; Fig. 3 is a vertical sectionaldetail view, on an enlarged scale, showing the connection of the movableflue with the outer flue of the air conduit, and the method ofconnecting the outer foot-plate with the inner foot-plate; Fig. 4 is avertical sectional detail view, on an enlarged scale, of the innerportion of the movable flue of the ventilator, in position.corresponding to that of Figs. 1, 2 and 3, and showing the connectionwith the inner transverse flue and the relation of the inner foot-plateto the finish-flooring of the vault; and Fig. 5 is a vertical transversesection on the line 55, Figs. 1, 2 and 4, the parts being shown on thesame scale as Figs. 3 and 4.

1 represents a portion of a fire and burglar proof vault of knownconstruction. 2 is the vestibule thereof, 3 the inner door frame,adapted to be closed by doors 4 (Fig. 2) and 5 the outer door frameadapted to be closed by the door 6. It has heretofore been oustomary toventilate vaults of this character by the introduction of a removableair suction conduit, usually through the upper portion of the doorway insuch position as would offer the least inconvenience to travel in andout, said ventilator being removed and laid to one side on the outside0f.the vault when it became necessary to close the doors.

According to our invention, we employ a movable conduit section or flue7 adapted to assume a position across the thresholds of the doorwayswhen the safe is open, and to connect at its respective ends with aninner air flue 8 or other air space, from which it is desired to exhaustair and with an outer fixed flue 9 (preferably beneath the flooring ofthe outer room), which leads to any suitable point of discharge or ofconnection With an air exhaust means; said movable conduit section beingadapted to support a foot-way to facilitate passage over it to reach theinterior of the vault. The foot-way is preferably constructed with anouter removable inclined foot-plate 10 which may be placed to one sidewhen the vault is closed, and an inner foot-plate 11 mounted upon theflue 7 and carried with said section into and out of place as the flueis withdrawn to permit closing or return to position of use when thevault is open. Flue 7 is preferably mounted through a hinging joint 12,in a frame 13 secured within the vault in such position as to bring thefoot-plate 11 on a level with the finish-floor 14: within the vault.Said section is provided with an intake 15 of such construction that itmakes a suitably tight connection with the air space 8 when the sectionis in position of use, and a discharge end 16 which fits into thevertical leg 9 of the flue or conduit 9 when the section is in theposition of use.

Referring to Fig. 3, it will be seen that the outer discharge end 16carries a packing 17 that flts a frame 18 at the upper end of the flue9-9 which frame is also preferably provided with a screen 19 to protectthe mouth of the flue. swinging flue 7 is provided with an oifset 20beyond which its foot-plate projects as at 21, to provide an interlockfor the outer footplate 10 which is preferably mounted on a frame 22formed with a bearing foot 22 and an end 22 that projects beneath theoverhanging end of the foot-plate. 7

By reference to Fig. 4, it will be seen that the inner end of themovable flue 7, is provided with a deflecting end 24 which fits withinan opening formed in the frame 13 that supports the hinge 12 andprovides a guard around the hinge.

The inner transverse flue 8 is preferably connected by downtakes 25 withcollecting flues 26 that extend along the upper portion of the vault,for the purpose of drawing air from the warmer part of the area to beventilated.

When the parts are in the position shown by full lines on the drawings,an air current set up in the conduit, either by suction at an externalpoint or by pressure developed within, will cause the air of the vaultto be withdrawn and replaced by fresh air from the outside. When itbecomes necessary to close the vault, the outer foot-plate 10 iswithdrawn, the movable flue 7 is raised upon its hinging end until itassumes the position shown in dotted lines in Fig. 1, where it will beself-sustaining by the construction of its hinge, and the doors may thenbe closed in the usual way. Upon opening the doors, the movable flue isreadily lowered to position of use. In its movements, the movable fluecarries the inner foot-plate 11 with it, moving it alternately from theposition in alinement with the inner finishing floor of the vault to aposition where it will be out of the way of the doors in closing thesafe. Then the flue is raised, the outer foot-plate 10 may be placedover the outer flue 9-9 in order to provide a place to stand whilemanipulating the outer door.

We do not limit ourselves to any particular construction of the innerand outer flues. The outer flue may be made of sheet metal piping ofdesired section, while the inner flue running transversely of the vaultjust inside the vestibule, may be formed by the bottom masonry, thetransverse floor beams and the flooring, or one of said beams and theinner facing of the vestibule frame. The movable flue, while preferablymade in the form shown in Fig. 5, may obviously be of different form orproportions and its outer end The outer end of the i i may be given suchshape as desired, to properly conform to the doorway through which it isto project. i

, Having thus described our invention, what j we claim and desire tosecure by Letters Patent is:

1. In combination with a safe or vault, a ventilating conduit comprisingan outer flue and a movable flue adapted to communicate j with the outerflue and movable into and out of a position extending across the bottomof l the vestibule. I

2. In combination with a safe or vault, a

ventilating conduit comprising an outer flue and a movable flue adaptedto communicate with the outer flue and movable into and out of aposition extending across the bottom of the vestibule said movable flueproviding a foot-way across the vestibule.

3. In a ventilator for vaults, the combination. of an outer flue, amovable flue adapted to connect with the outer flue and lie across thebottom of the vestibule, and a foot-plate carried by the said movableflue.

4. In a ventilator for vaults, a movable flue hinged at one end withinthe vault, and movable upon said hinge into and out of a position lyingacross the bottom of the vestibule, and means cooperating with saidmovable flue to direct an air current there through.

5. In combination with a vault, an inner ventilating flue, and a movableflue adapted to communicate with said inner flue and to be moved intoand out of position across the bottom of the vestibule.

6. In combination with a vault, having an inner floor and an inner fluebelow the floor, a movable flue carrying a foot-plate, and adapted tocommunicate with the inner flue, and movable into and out of positionacross the bottom of the vestibule.

7. In combination with a vault, an inner ventilating flue leading from aportion of the vault to a space within the vestibule, a movable fluemounted upon a hinge within the vestibule movable to bring it intocommunication with the inner flue and into communication across thebottom of the vestibule and an outer flue with which said movable fluealso communicates when lying across the bottom of the vestibule.

8. In a ventilator for vaults, the combination of the inner and outerfixed flues and the movable flue having hinging connection at one of thefixed flues and movable into and piut of communication with the outerfixed 9. In a ventilator for vaults, the combination of the movable fluemounted upon a hinge within the vault movable to a position across thebottom of the vestibule, providing a foot-Way thereover, and projectingbeyond the vestibule, an outer flue with which the movable fluecommunicates when in said projected position, and an outer foot-platesipported by the projecting end of the mova e which the movable flueconnects when in 15 horizontal position substantially as set forth.
